[RFC PATCH v1 2/6] btrfs: Change `mount_opt` type in `struct btrfs_fs_info` to `u64`

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

On a 32-bit Linux system, `unsigned long` is 32-bit. In preparation to
add more mount options, change the type to `u64` because the enum for
this option has reached the max 32-bit capacity.

It does not make any difference on a system where `unsigned long` is
64-bit, only needed for the 32-bit system.
